T o all whom 'it may concern.:

Be it known that I, ALVIN C. PANooAsT, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Culinary Separating-Machines, of which the following is a full, clear, and exact description.

The object of this invention is to produce certain new and useful improvements in culinary utensils.

The invention relates to culinary vessels equipped with mechanism adapted to crush,

oif the juices or liquid port-ions of' foodstuffs fromthe more solid matters containing them' as may be required.. in the preparationvof various articles for edible consumption, such as the meshing of potatoes7or'the like or the mashing of fruits and separating or straining of their juices or the extraction of soup materials, either meat juices or thin vegetable preparations all in a practically 'continuous operation. It is adapted for all of, these uses in the precise form shown and with slight changes or modifications might readily be adapted for other analogous uses.

AnA important' feature of the invention lies in such construction of its detachable parts or 4members that it may be quickly and easily taken apart and every portion or surface of every member made readily accessible for thorough cleansing.

In the drawings which show the invention 1n its now preferred form of details and general assemblage of parts, Figure 1 is a side elevation, partly in sect-ion on the linel 1-4-1 of Fig. 3, of a device embodying the essential features of the invention. Fig. 2

is a similar view,taken at a right angleto Fig. 1, partly'in section on the lines 2-2 of Figs. 1 and 3.' Fig. 3 is a plan. view with cover of feed hopper removed'. Fig. 4 isa horizontal sectiononthe line lt-4 of Figs. 1 and 2. Fig. 5 is -an inverted view of the bottom of the strainer vessel. Fig. 6 is a side elevation of the main driving shaft and the'cross arms carried thereby. Fig. 7 `is an inverted or bottom plan View ofthe upperl cross arm, showingY the shaft in section on the line 7- '71of Fig. `V6. Fig. 8l is a side elevation of one l,of the centrifugal crushing rollers and its supports, detached and partly broken away and partly in section on the lines 8-8 of Figs. 6 and 7. Fig. 9 is a side elevation of one of the V sectioned members of the vertical bars of the roller frame. Fig. 10 is a section of the same on the line 10-10 of Fig. 9. Fig. 11 is a similar view to Fig. 9 of the other V sectioned member of the vertical bar. Fig. 12 is a section of the same on lines 12--12 of Fig. 11. Fig. 13 is an elevation of a portion of the vertical flange of an'annularsupporting ring carried at the top of the strainer vessel and secured `by bayonet joint connection to said vessel. mash, mix or agitate and separate or strain Referring to the parts by letters, A is a tight cylindrical outer vessel having a conically inclined tight bottom a, to the high center of which is secured a' cent-ral step bearing a. It is also provided with a suitable faucet Azwhereby its contents may.

dimensions as will admit support certain driving mechanism and\` gears-to be hereinafter described; the covery B having a central aperture b2 for the passage of portions'of this mechanism. f X

Within the vessel A is a rotatable cylinf drical strainer vessel D/the side walls of which are mainly composed of finely per-` forated metal sheetshne screens, or wire, gauze, to constitute 'a strainer sieve through which the desired products are forced.

These walls are reinforced on their exterior side by small vertical ribs D. The bottomv its periphery, and provided on its lower side -with a central boss d from which radiate bearing d3 while projecting from its bottom is a trunnion pin d4 adapted to engage the step bearing aof the outer'vessel.

At its upper end the strainer vessel D isr provided with an inner annularL band E. having an inclined ange to stren then -and stifen it. This Aar'inular band E 1s red is preferably solid,`ci1rved .ordished up at movably secured to the strainer vessel D by bayonet slots e5 (see Fig. 13) which engage rigid studpins (Z5 projecting inwardly from the surface' of the vessel. See Fig. 1. A cross bar E is secured by its feet e to the flange e and is bowed up at its central portion and provided with a boss E2 centrally bored to form a shaft bearing, and having a sleeve hub e2 extending well above the top of the boss and squared at its upper end as at e". An oil-drip cup es is formed about the lower portion of the sleeve to catch any lubricating oil dripping down from the gearing, etc.'above it. A shaft G on the axis of the vessels A and-D is supported by a trunnion pin g at its lower end taking into `the step bearing Z3 on the vessel D and at.

its upper end in the bearing boss/E2 of the cross bar E. Cross arms Hand I are rigidly secured upon the shaft Gr near its v upper and lower ends respectively and they support crushing rollers in a manner that will presently be explained.

Upon the frame standard C is secured a bracket between the ears C2 of which an arm F is mounted upon a pivot pin c. This arm extends acrossthe frame and its free end is connected to and supported by a gear casing J rigidly mounted on the top of the standard This arm rests upon a lug j projecting fromv the gear casing. The upper side f of the cross` arm, at this end, projects beyondA the lower side, is centrally notched as at f and is kadapted to fall into undercut recesses j on the inner face of the gear casing. Between these recesses is a rib j2 embraced by the notch f of the arm, and in this-rib is formed a cross groove 7'8 adapted to be engaged by a laterally swinging latch f3 pivoted at f2 on the, arm F and provided with a pointed locking screw f4 which engages an indentation fs'in the upper face of the arm. WV hen the latch is swung to the straight Aposition shown by full lines in Fig'. 3,'tlne` arm F is locked, but when the latch isswungto the dotted position, this end of the arm is freed and' may be raised.'

ofthe step lug j.' c The,l gear casing J incloses a train of wheels adapted to drive the final shaft L through power from the fly wheel K which may be turnedby hand crank or other power, as desired. The train of gearing is similar to that shown 1n Letters Patent No.

*901,465 granted to me October 20, 1908, and

it is not specifically claimed herein as a part of this invention. Itis adapted to reyverse the directionof revolution of the final mounted in the arm F, to drive certain gear' shaft 7c when desired. Upon the yproj ecting end ofthe shaft 7c is mounted a clutch disk-5 c 'having a pair of clutch teeth k2 set out near the periphery. A counter shaft L those on the clutch disk 7: and adapted to pass through the opposing teeth of that disk when the arm F. is being swung, but otherwise to engage them when the counter shaft L is to be operated.

At mid length of the cross arm F is formed a round open bracket or casing F for the inclosure of a set of driving bevel gear wheels, the casing having detachable covers F2 and F3 suitably secured thereto. The counter shaft L projects into this casing and has a bevel wheel Z3 rigidly attached to it. This wheel engages a bevel wheel M having a lower hub in which is a square socket adapted to fit over the upper squared end e4 of the sleeve hub e2 on the cross arm E on the strainer vessel, and impart rotary motion to said vessel. The wheel M has also a long upper sleeve hub m which has bearing'in the central huh F4 of an integral cross arm F5 extending across the casing. See Figs. 1, 2 and 3. Another bevel wheel N engages the wheel Z3 and is rigidly secured on a short shaft a rotatably mounted in the sleeve hub m of the lower bevel wheel m. This shaft has a square socket n at its lower end adapted to engage the squared upper end g of the shaft G and rotate it in an opposite direction to the rotation of the strainer vessel I). A reduced portion n? of the shaft a extends through the top cover of the casing and carries a rigid hand wheel N" by means of which the shaft n may be vturned by hand to adjust the several square socket joints and also the clutch teeth Z2 when assembling the parts to operative positions.

By the just described arrangements of the parts the overhangng arm F may be lifted out of the way and the square socketed connections of the shaft G and the arm E with their driving gears separated in about the same plane within the casing F2 of the arm F. This removes all obstructions from above the cover B which may then be lifted off to afford free access to the interiors of the vessels A and D.

A rotatable carrying frame composed of the cross arms I-I and I rigidly fixed to the shaft G, is adapted to pivotally support centrifugal crushing rollers O having pins o, 0 on their ends which take into bearings p and (I on the free ends of link members P and Q r which are mounted on pivot pins 7L and c' of the respective cross arms. The outer ends of these link members are offset as at p and g to give greater space between these outer ends for the rollers O. These link members are provided with connecting bars P and Q which stand at right angles to the link portions, and are generally V- shaped incross section, (see-Figs. 10 and 12), and so relatively proportioned that the smaller bar P will fit or nest into the bar Q as shown in Fig. 8 and by dotted lines in Fig. 12. At its extremities the bar Q' is provided with integral cross plates g2, g2 ,which for short distances inclofse the outer open face of the V and are intended tovhold the bar P against displacement. These plates necessitate the telescopic assembling of the two bars, the bar P slipping into the V recess of the bar Q and inside of the plates q2. These bars P and Q or at least one of `them is long enough to limit the movement of the link members toward each other and hold them at proper distances apart to insure their suitable connection on the pivot pins L and c' of the carrying frame.

It will be observed that when the parts are assembled the point of the Vsectioned bar is in the front or advance face of the bar, thereby facilitating its progress throug 1 the mass of materialv in the strainer vessel to be operated upon. The pivot pins kqon the upper cross arm, project from recesses zf formed above the generalplane of the lower surface of the arm and bounded on one side by lugs or blocks k2 extending below said general plane of Athe arm, (see Figs. 6, 7 and 8), said blocks being upon the advance or forward 4side of the arms with respect to their operative direction of rotation, these .lugs also prevent .setting arms in wrong direction. In assembling these parts :the two bars P and Q. are tele-V scoped as described, their` link members closing upon the'ends ofthe rollers and en# gaging their bearing pins o, 40 as shown in Fig. 8. This group of parts which I will call the roller frame is then pivotallyconnected to the cross arms H and I by first' engaging the link member P with the stud pin JL of the upper arm H, the link` members P and Q' for this operation being positined in radial line with the cross arms so that the inner or pivoted end `of the 'link member P will be in line to register with .a-nd sink into the recess i atthe end of the arm H, thus allowing the roller frame tohe raised sufficientlyv to permit of the lowerlink member Q, being slipped upon the `pin z' of the lower arm I. The roller frame is then lowered until link member Q, rests upon the shoulder at the base of pin,z',the

upperA pin being long enough'to admit of this movement without disengaging it from the link member P. The' roller .frame is then turned to its/operative position, shown by full lines in Figs; 4, 7 and 8, at nearly a\right angle'lto the cross arms, in which position the up er surfaces of the link memfber P rest against the lower surface of the crossyarm H and cannot, unless' turned back, become disengaged from the pivot pin` h.' Otherwise cross arm I and the lower surface of the cross arm Hl are the same as that froml outside to outsideof the bearing faces of the link members Pand Q,and this holds the roller frame against.. any escape from its pivot pins untilit is again turned to positionor register with the recess la of the upper arm Where the link member P may he moved int-o it. These members of the roller frames must be assembled and pivotally mounted in the carrying frames H, I, beforebeing placed in the strainer vessel D, their position in which prevents the roller frames from being turned to radial positions on the carrying frame and becoming disengaged from its pivot pins h and z'.

When the various elements are assembled as described, the driving mechanism and its gears rotate the strainer vessel D in one direction and the carrying frame G, H, I with'its link supported rollers O in the opposite direction, the rotation of the carrying frame being sufficiently rapid to impart con siderable centrifugal force to the rollers and press them against the oppositely moving walls of the -strainer vessel. Any matter, vegetables, meats, fruits, etc., to be acted upon is fed into hopper b andV` falling into vessel D is carried and held by centrifugal action against the strainer walls of said vessel. It is there pressed upon by the rollers O and either mashed and. forced through thestrainer, or it is crushed and itsjuices expressed and forced through the strainer, the pulp remaining in the vessel. The ex pressed juices or other matters are collected in the outer vesselA and there kept in a state of agitation by the fin blades d on the bottom of the vessel D and by the slight ribs D on its outer side walls. The produ/ cts may be drawn off as desired through faucet A.

- The general arrangement and assembling l' of the several parts constitute an exceptionally useful culinary machine for the purposes mentioned, and the construction of its detailed parts admits of their being. held in assembled positions' without the use of bolts, screws, pins or similar, small detachable devices. This facilitates ithe machine parts being disconnected forl cleaning. All.

of the parts wtoo are specially designed withopen surfaces easily accessible for cleaning.
